Machine intelligence is the last invention that humanity will ever need to make.

The greatest existential risks over the coming decades or century arise from certain, anticipated technological breakthroughs that we might make in particular, machine super intelligence, nanotechnology and synthetic biology. Each of these has an enormous potential for improving the human condition by helping cure disease, poverty, etc. But one could imagine them being misused, used to create powerful weapon systems, or even some kind of accidental destructive scenario, where we suddenly are in possession of some technology that's far more powerful than we are able to control or use wisely.

The Internet is a big boon to academic research. Gone are the days spent in dusty library stacks digging for journal articles. Many articles are available free to the public in open-access journal or as preprints on the authors' website.

It’s unlikely that any of those natural hazards will do us in within the next 100 years if we’ve already survived 100,000. By contrast, we are introducing, through human activity, entirely new types of dangers by developing powerful new technologies. We have no record of surviving those.

Are you living in a computer simulation?

We would want the solution to the safety problem before somebody figures out the solution to the AI problem.

The challenge presented by the prospect of superintelligence, and how we might best respond is quite possibly the most important and most daunting challenge humanity has ever faced. And-whether we succeed or fail-it is probably the last challenge we will ever face.
